Aurora is planning to participate in an event at her schools field day that requires her to complete tasks at various stations in the fastest time possible. to prepare for the event she is practicing and keeping track of her time to complete each station. the x coordinate is the station number and the y coordinate is the time in minutes since the start of the race that she completed the task.
( 1, 2 ), ( 2, 4 ), ( 3, 8 ), ( 4, 16 )
A: is this data modeling an arithmetic sequence or a geometric sequence? Explain.
B: Use a recursive formula to determine the time she will complete station 5. Show your work.
C: Use an explicit formula to find the time she will complete the 10th station. Show your work.​

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°

step-by-step explanation:

unless you made a typo, the answers are both a and c.

step-by-step explanation:

1.5/3 is .5 whereas 3/9 is .3333333 not proportional

22/33 is .66666 and 4/6 is also .66666 proportional

2/4 is .5 whereas 142/213 is .66666 not proportional

14/7 is 2 and 7/3.5 is also 2 proportional

you could've also checked it by doing this simple division:

if the larger fraction divides with the smaller fraction to equal 1, it is proportional. so let me show you what i mean:

when i divide 22/33 by 4/6 i get 1, so we know it is proportional, and it is the same with 14/7 and 7/3.5. now if i divide 3/9 by 1.5/3 i get .66666 so therefore we know it is not proportional.

there are many ways to do this so i wanted to show you some possible ways.
